I'm just starting out with electronics and I've found this diagram of a battery powered sound amp. I thought this would be a cool project to do for my guitar. I'm only in grade 9 and I've learnt about ohms law. I can read switches and resisters off a circuit. Other than that I'm stuck!

Please could someone help me with the layout of the circuit and tell me what are the exact parts that I will need.

This could be somewhat difficult if you don't have the means to make a printed circuit board. An alternative would be to go to www.circuitspecialists.com and get a bus strip to breadboard the circuit on. Their #WB-102-1+J is only $6.49. They have small parts, too.
